3 o Symptoms usually warn a person that they re ill o Without symptoms, people infected with an STD don t know they re infected so they don t get treated and can spread the infection o STDs that are asymptomatic can be detected only by lab tests o Some symptoms may not appear until years after the person is infected People often don t talk about STDs because they re embarrassed o often too embarrassed to see a doctor and go untreated which increases the likelihood that they ll spread the disease STDs Are Serious STDs can cause serious problems even years after one is infected If not treated, can lead to infertility (inability to have children) Can cause serious illness or even death People who are sexually active should undergo regular testing for STDs STDs and Teens Teen behavior places teens at higher risk of catching STDs 1 in 10 teens is infected with an STD Among teens who are sexually active, 1 in 5 has an STD High-risk behaviors: o Being sexually active (only abstinence eliminates the risk) o Having more than 1 sexual partner o Having a sexual partner who has had multiple sexual partners o Using alcohol or drugs Most effective way to protect from STDs is to remain abstinent before marriage and marry someone who has also been abstinent and is uninfected Teens Are at Higher Risk Teen bodies may not fight infections as well as bodies of healthy adults Females are at higher risk of catching STDs o Females have large areas of mucous membranes (the moist, pink tissues that line the openings into the body) that can be exposed to infectious particles during sexual intercourse o During sexual intercourse, females receive a larger volume of potentially infected body fluid than males do o Cells on the cervix of teenage females are more susceptible to infection than the cells of the adult cervix Preventing STDs Remember you re special; friends and family care about you No one can protect you from STDs but you; stand up for yourself and take control Practice abstinence Stay away from drugs and alcohol Respect yourself (less likely to give in to pressure) Learn the facts about STDs and use those facts to make good decisions Choose friends who influence you in a positive way Get plenty of rest (so you think clearly) Go out as a group
